In many Pokemon fanfics, Eevee can evolve in unique ways compared to the official games. For example, it might evolve due to a special bond with a trainer rather than just using stones or leveling up at a specific location. Some fanfics might introduce new evolutionary triggers like a rare item found in a secret area or a once - in - a - lifetime event.
The story of Pokemon Fire Red is about a young trainer's journey in the Kanto region. The trainer starts with a single Pokemon and travels across various cities, battling Gym Leaders to earn badges. Along the way, they encounter Team Rocket causing trouble, like stealing Pokemon. Eventually, they aim to compete in the Pokemon League and become the Champion.
If we consider the common growth pattern in the Pokemon series, Charmander evolving into Charmeleon could be an early evolution in the fanfiction. Since Charmander has a clear evolution line and Ash has a strong bond with it, it would make sense for it to be one of the first to evolve, perhaps due to a tough battle or a special encounter that accelerates its growth.
In the Rock Kingdom, the Fire God could evolve in the fire furnace of the mantle of Vesuvius. In order to evolve into the Raging Fire God, he first needed to raise the Fire God's level to level 100 and prepare the fuel rod and flaming glass. The fuel rod could be obtained by defeating the Pea Dragon at the maintenance station, while the flaming glass could be obtained by defeating the cute ape at the center of Vesuvius. After the evolution, the Fire God General would become the Raging Fire God.
Definitely Red. He's the iconic protagonist of the game, and there are so many ways to expand on his story. You could write about his post - game adventures or what he was thinking during his original journey.
One idea could be a story where the main character discovers a hidden, powerful Pokemon that no one has ever seen before in the Kanto region. This Pokemon could have unique abilities that change the way battles are fought.
Ash is often a very popular character. His experience and determination make him a great fit in stories involving Mega Evolution. He could be on a quest to master Mega Evolution for all his Pokemon.
